Aren't we already sort of in a worst of both worlds situation here? The IDs we are using as primary keys are from the SSA. The FHA is involved in most American's mortgage decisions. The Stafford loan program in most of America's student loans.

But we also have giant for-profit companies aggregating giant databases with little to no oversight, and up until recently no ability to access your own data for free, and still today no straightforward, across-the-board, means to appeal bad data, or collect damages from it (or from leaks of it).

Even with the terrible things associated with the no-fly list there is a TSA appeals process and a court system to challenge it. Do you know how you correct mistakes in your Equifax-TransUnion-Experian composite credit score? You mostly don't, and you most likely can't take them to court, because they think you are bound to arbitration.

I don't know if there is a good solution here either, but at least a government-run solution would have to be accountable to the people as citizens/constituents (even if it would still likely be in the pocket of the banks).
